Astronomers use Kepler telescope to study weather on Jupiter-size planets beyond our solar system

The bright lights from these hungry black holes revealed a subtle background field

Seventy years ago the renowned astronomer undertook a daring rescue of the renowned physicist as the Red Army swept across a defeated Germany.

The first results from the upgraded Large Hadron Collider, syntactic foam, a Fibonacci clock, and a worm with a fractal nose glove are among this week's highlights.
